Q. How to Upgrade version 1.64 to 1.66?
A. Please download the installation package of version
1.66 and install it into the directory of version 1.64.
It will only upgrade version 1.64 to 1.66 and will not
change the database. Anyway you'd better backup the
whole directory of Catalog Max before you install Catalog
Max 1.66.
